This invention relates to swings and particularlyvtoxthat .typeof swing having a seat carried by smeans. off flexible suspending members and aisolhaving operatingcmeans.

Thesprincipal object of the instant invention is.-.the provision of a, suspended swing having a propulsion or -operating means that permits of freespivotal movement of all the working parts whemthe swing ism-motion.

Aifurther object" of this invention is the provision. of a seat-member suspended by a pair of -front and a pair of rear flexible suspending members, a pivotallysuspended foot rest carried by-bars pivotedintermediateztheir ends to the seat-member, and-a-pivotally mounted link interconnecting each of said arms to its adjacentsuspending member; whereby the suspending members will be flexed as the foot rest is moved relative to the seat member.

Other objects are sturdiness of construction, easeof operation and adjustability to accommodate persons of difierent statures.

Reference will now be had to the drawing, wherein:

Figure 1 is a perspective view of a swing embodying this invention.

Fig. 2 is an enlarged, end elevation of the swing, with parts broken away for clearness.

Fig. 3 is an enlarged, sectional view, taken on line III-III of Fig. 2.

Fig. 4 is an enlarged, fragmentary view of a portion of the frame and arm, with the flexible supporting member attachment shown in elevation.

Fig. 5 is a vertical, sectional view, taken on line V-V of Fig. 2, and,

Fig. 6 is a fragmentary, sectional view of the front portion of one of the arms showing the pivotal connection of the foot rest carrying bar.

Throughout the several views, like reference characters will designate similar parts and the numeral I0 indicates a seat member comprising base members [2, arms l4, vertically disposed back members l6 and. front posts l8. Back members and front posts are positioned and interlocked with base members 12 and arms l4 so as to form a rigid structure when the seat bottoms and back boards 22 are secured in position. The front posts are held in operative position with base members l2 by means of cleats 24 and angleiron 26 which has its vertical leg facing against post l8 and its horizontal leg extending rearwardly on the bottom of base member l2 where it is attached by means of screws 28 and the tie rod 30.

This-tie rod-has an -eye-'12at'its-upper end and extendsdownwardly througharm M; thence through base member I 2 and angle iron- 26*where it is secured by'means-of a-nut--32 which engages the threaded end '34 of 'the -tie-rod. For the;purpose of quickassemblage, a dowel pin 36is;provided for positioning the frontpost-l 8'gto the base member 12: Front postsl8 are secured to, the arms M by screws or other suitable:- fastening, means 38.-

The swing seatris-suspendedby any suitable flexible members so as to permitifree movement of the swing in any direction, 'Iheseflexible suspension; members are shown as chains, 40' which are-positioned at, the proximal'corners, of the swing. The rear pair .of chains 40'are interconnectedwithlinks 42which in turn are pivoted on bolt 44 extending through arm l4 and back member I6. This bolt serves also to tie together the parts of the swing frame.

The front pair of flexible suspension members is attached to the seat member through the intermediacy of links 46 and the tie rod 30, as clearly shown in Figs. 2 and 5. Arms M are projected forwardly of the seat proper and are each provided with a slot 48, into which is fitted a vertically disposed bar 50. A pin 52 extends transversely through the arm and the bar 50, thereby pivoting the same intermediate its ends.

Bar 50 is tubular in form and is provided at its lower end with a telescoping rod. 54 which is secured thereto by means of a bolt 55. A series of holes 58 formed through the lower end of 50 permits of vertical adjustment of rod 54. Carried by rods 54 and secured thereto by nuts 60 is a foot board 62. This foot board extends entirely across and in front of the swing seat so as to be accessible to the occupant, regardless of his position in the swing.

The upper portion of bars 50 extends above arms l4 and in substantially parallel position with chains 40. A connecting link 64 pivotally mounted in bar 50 at 65 as shown in Fig. 3, extends rearwardly in a substantially horizontal position and is pivotally connected at its rear end with chain 40 through the intermediacy of perforated plate 66, washer 68 and nut 10.

It is very evident that with this type of structure no sliding movement other than the rotary movement of the pivotal parts is present when the swing is in action. It is apparent that a straight perforated bar might be substituted for link 64 by simply using pins to connect it with bar 50 and chain 40, thereby obtaining the same general efiect in so far as the relative movements of the parts are concerned.

During the operation of propelling this swing by means of the parts provided herein, it is very evident that bolt 44 will move through an are having its center at 12, while the point 65 will move through an arc whose center is at 52, thereby maintaining 64 in a position substantially. parallel with arm 44 without any relative sliding movementof the parts.

The most important feature of this invention is I the mannerin which force is transmitted from bar 50 to the flexible suspension member 44,-

which permits of a very definite and easy move-' ment of-the flexible member either forwardly or.

rearwardly and without any undue wearing action of the parts. The upper end 14 of bar 50 may be utilized as .a hand hold for'operating the swing.

It islnot desired to limit this invention to the V construction shown and described since many modificationsmay be, made within. the scope of the appended claims without departing from the spirit thereof. 7

oHaving thus described the invention, what is claimed as new and desired to be secured by Letters Patent .is:

1. Ina swing having a seat member suspended pair of front and a pair of rear flexible suspending members and having end arms extending forwardly of said seat member; a vertically disposed bar pivoted intermediate its ends in each of said arms; a foot rest extendingacross the front of said seat member carried by said bars; a link pivoted adjacent the upper end of each of said bars and to the respective adjacent suspending member intermediate its ends whereby said suspending members are simultaneously fiexedas the foot board is moved relative to the seat member; and means to vary the distance from the seat to the foot rest. I V

3. In a swing having a seat member, an arm at each end respectively of said seat member, ex-

tending forwardly beyond the front edge of said seat member, and flexible members suspending saidseat, at the ends thereof 7 adjacent the front and rear edges respectively, the combination of a foot rest below the seat along the front edge thereof; a bar at each end'respectively of said foot rest for carrying the same; and a linkinterconnecting the said bar and theproximal front; 7

of the respective bar, saidlinks-each being piv- 1 otally joined to their respective bariinter'mediate the upper end thereof and its pivotal connection with the arm whereby to provide an upwardly projecting portion to serve'as a grip for the op-' erator, said links being attached to the front fiexible'members at a point intermediate'their ends to permit flexing thereof as the foot rest-is swinging. about the pivotal connections between 5 the bars andarms.
